ISL69133IRAZ-T7A

Special Purpose Regulators Overview

The ISL69133IRAZ-T7A is a digital dual-output, configurable multi-phase PWM controller designed for Intel VR13 infrastructure power applications. It supports flexible phase allocation with a maximum of four phases (X+Y ≤ 4). The device features an SVID interface and PMBus v1.3 support for configuration and monitoring. It operates with an input voltage range of 4.5V to 25V and provides two outputs adjustable from 0V to 3.05V. Packaged in a 40-WFQFN (5x5) surface-mount package, it is rated for operation between -40°C and 85°C.

Special Purpose Regulators Feature Summary

• Digital control architecture compliant with Intel VR13 specifications
• Configurable multi-phase topology supporting up to four total phases across two outputs
• Integrated SVID and PMBus v1.3 interfaces for system communication
• Proprietary digital linear synthesis current modulation for transient response

Special Purpose Regulators Applications

• Intel IMVP8 platform microprocessor core power rails
• High-performance server memory power supplies
• Infrastructure power solutions requiring VR13 compliance

Special Purpose Regulators Procurement Notes

Verify the specific ordering suffix T7A corresponds to the tape-and-reel packaging format required for your assembly line. Confirm that the 40-TQFN footprint matches your PCB design guidelines. Check the latest Product Change Notification (PCN) documents for any updates regarding assembly facilities or label changes that may affect integration timelines.

Special Purpose Regulators Selection Notes

Select this component when designing systems requiring strict adherence to Intel VR13 standards with limited phase counts. The dual-output capability allows independent regulation of core and memory rails within a single controller. Ensure the application requires SVID or PMBus compatibility for dynamic voltage scaling and monitoring functions.

Special Purpose Regulators Part Context

This part belongs to the Renesas ISL691xx series of digital power controllers. It is specifically engineered for infrastructure and server-grade applications where high efficiency and precise transient response are critical. The device integrates advanced fault management and diagnostic features to ensure system reliability in demanding computing environments.

Special Purpose Regulators Replacement Considerations

The ISL69122IRAZ-T7A is a related model but supports up to seven phases, offering higher flexibility. For direct pin-compatible alternatives within the VR13 family, consult the official Renesas cross-reference guide for updated generations or enhanced feature sets.
